I don't think tptacek is saying that good posts don't exist on HN, of course they do. The problem is that the signal-to-noise ratio is so low nowadays that it's hardly worth wading through all the hyper-politicized vitriol just to get to it. The amount of horribly bad posts on HN has reached a proportion where they're no longer exceptions, they characterize the site as a whole. Personally I've noticed my participation drop in the last few months because of this. There are fewer and fewer people interested in engaging in a discussion, and more and more religious zealotry where it's clear poster has zero interest in opposing views, and will stoop consistently to hostility and fundamental indecency when confronted.
